Using Tuple types in TypeScript enables us to create typesafe rest arguments:
type Params = [string,number,string]
const fn = (...args: Params) => null
// Type is (args_0: string, args_1: number, args_2: string) => null
Is there a method to assign specific names to these parameters within the Type realm?
Instead of default names like args_0, args_1, args_2, I am seeking a way to explicitly name them (e.g. myString, myNumber, mySecondString).
When utilizing tuples in TypeScript, assigning names to the tuple members allows for easier spread into function arguments:
type Parameters = [myString: string, myNumber: number, mySecondString: string]
const customFunction = (...args: Parameters) => null
// const customFunction: (myString: string, myNumber: number, mySecondString: string) => null
Allow me to present an example to demonstrate my current objective. const v1: { type: "S"; payload: string } = { type: "S", payload: "test" }; const v2: { type: "N"; payload: number } = { type: "N", payload: 123 }; type Actions = typeof v1 | typeof v2; ...
